Migrate from using mutagen directly to use mediafile overlay library
Library is created for Beets - music library manager and MusicBrainz tagger.
https://github.com/beetbox/mediafile
I had pleasure to work with authors and do some MRs.
Library is very easy to use, makes all tagging code generic and not dependent on underlying file format.
This could allow us to cut of lots of tag import code and as a bonus allow more formats like MP4.
Library itself uses mutagen, but creates user friendly high-level overlay on top of it.
I'd like to see some comments about the idea ;)
